左冠状动脉主干部完全阻塞引起的急性心肌梗塞(AMI-LMCA)时累及的面积广泛,病情危笃,对其进行早期的诊断与正确的治疗是很必要的。作者分析从1980年12月至1984年1月间就诊于仓敷中央医院心脏病中心,进行紧急冠状动脉造影的72例急性心肌梗塞病例。其中5例确定为左冠状动脉主干部的完全阻塞,来诊时病情危笃,均处于休克状态。其心电图所见是,Ⅰ、avL 导联上均呈现 ST 段抬高,而于胸前导联未见广泛性 ST 段抬高。5例中4例做了经皮冠状动脉腔内血管再通术(PTCR),全部病例的血管再疏通。5例均应用主动脉内气囊
Acute myocardial infarction (AMI-LMCA) caused by complete occlusion of the left main coronary artery is extensive and of high risk, and early diagnosis and proper treatment are necessary. The authors analyzed 72 patients with acute myocardial infarction undergoing emergency coronary angiography from December 1980 to January 1984 at the Cardiovascular Center of Kurashing Central Hospital. Five of them were identified as complete obstruction of the left main coronary artery and were in critical condition when diagnosed. The ECG is seen, Ⅰ, avL leads showed ST-segment elevation, but not in the anterior chest lead extensive ST-segment elevation. Four of the five patients underwent percutaneous transluminal coronary revascularization (PTCR) and all the cases were re-dredged. 5 cases were used intra-aortic balloon
